Abstract
A disposable diaper includes an absorptive body having a liquid permeable topsheet, a liquid impermeable backsheet, and a liquid retentive absorbent member interposed between the sheets and a pair of flaps connected to the lateral edges of the absorptive body. The disposable diaper has a pair of upstanding walls which are formed by providing a sheet at the lateral sides of the diaper, the sheet has a lateral base edge and a lateral distal edge and is arranged in such a manner that the sheet is folded to allow the base edge and the distal edge to be positioned on the side of the flap and that the longitudinal ends of the sheet as folded are fixed to a stomach side section and a back side section of the diaper, respectively. The upstanding wall includes a base portion formed by fixing the sheet to the flap or the absorptive body; a folded portion positioned on the inner side of the absorptive body and formed by folding the sheet; and a free end portion positioned further outward in the width direction of the diaper than the folded portion, the folded portion and the free end portion are each provided with an elastic member to stand the upstanding wall upward.
